Priced it out ... I can have the pin made in batches of 100 for 3.70 each ... then plus the screw and the washer. .... Figure about $5 per pin kit (1) my cost. Might be able to sell them for $10/pin.
Total market worldwide .... probably 2000 pieces at most .... ain't nobody gettin rich
But as opposed to trying to glue or plastic weld something that would probably break again, or trying to find a good used piece for $50-100, or a new repop $200. Might not be a bad option.
Wonder if any other late 60's cars use a similar pin for the grills.
